摘要
路表弯沉并不能完全反映土基顶面压应变,在路面结构设计中必需要重视土基顶面压应变的状态。鉴于此,采用典型路面结构,分析各结构层参数的变化对土基顶面压应变和土基内部压应变的影响,以为沥青路面结构设计提供参考。
The road surface deflection can＇t fully reflect the compressive strain of soil base, so the status of compressive strain on top of soil base needs attention in the pavement structure design. This paper uses a typical pavement structure to analyze the effect of change of the structural layer parameters on compressive strain on top of and inside soil base. It can provide reference for structure design of asphalt pavement.
